Full-fledged L.A. rockerdom doesn't happen overnight. First, you need the record. Then comes the look. In fact, that's how we prefer it. If you roll onto the scene with a tatted sleeve, smoky guy-liner, and a whoa nelly fauxhawk, you'll do nothing but raise a disbelieving eyebrow. But, if you manage a triple-platinum record, your feigned awesomeness will be excused—maybe even celebrated. You've earned the right to front in moderation. Here, we show you how Adam Levine—Maroon 5 frontman and a judge on NBC's surprise smash singing competition The Voice—has tadpoled from early aughts mallrat to a Top 40 poseur of solid repute.
